signed ints are supported to be returned from private functions, but aztec.js cannot deserialize them. this adds signed int deserialization support.

Why do we use abiType.width / 8 here? And wouldn't it be clearer to just work with a buffer than with a hex string? I admittedly don't understand the encoding much.

You make a good point, I have refactored the entire thing and added a comment why we use abiType.width. (It's just bits to bytes)

let ret = BigInt('0x' + newHex);
// Manual 2's complement
if (0x80 & signByte) {
ret = BigInt('0b' + [...ret.toString(2)].map(i => (i === '0' ? 1 : 0)).join('')) + BigInt(1);

It was a bit autistically written, have refactored to hopefully make it more understandable.

complete nit: slipping this logic into a function called parse signed integer would mentally simplify this a bit and signify that we are doing two's complement parsing

Fair point. Have slipped the logic into utils, and have written some tests for good measure 🙏
